All dimensions are approximate as gaskets can stretch or shrink to fit specific lids. Compatibility and fit tips: To ensure compatibility, measure your old gasket and pressure cooker pot. Sealing rings are manufactured to arrive up to 1 inch too large to accommodate normal shrinkage. Soaking your gasket in warm water for 10 minutes before installing can increase pliability. Use scenarios: - Replacing a worn or damaged gasket on a Mirro 4, 6 or 8 quart pressure cooker to restore proper sealing and pressure performance. - Keeping a ready spare on hand for busy kitchens that use Mirro 4-8 qt models. - Replacing after cleaning or storage to ensure reliable sealing and easy future use.
